Between 1933 and 1945, Nazi Germany established about 20,000 concentration camps and ghettos. These camps and ghettos were an essential part of the Nazis' systematic extermination of Jews, as well as the persecution and murder of political adversaries, homosexuals, intellectuals, artists, Poles, Soviet POW's, Romani people (gypsies), Slavs, Serbs, Freemasons, Jehovah's Witnesses, disabled and others considered socially and racially undesirable.

Following the Wannsee Conference in Berlin, January 20, 1942, Extermination Camps and the "Final Solution" became the Nazi regime's major obsession. Consequently, of the 6 million Jews murdered in the Holocaust, more than half were systematically exterminated in Nazi Death Camps between 1942 and 1945. - Camp Maps
